“…Protein in diet is digested and broken down to produce amino acids, which are directly used by organism (Wu et al, 2014). Adequate protein is necessary for optimal growth, but more than a certain amount of protein is not used for growth (Bansemer et al, 2015; Lalramchhani et al, 2019). Unused amino acids are oxidized and broken down to produce ammonia and urea, which are gradually accumulated in the blood and expelled from the body (Wu et al, 2014).…”

A 120‐day feeding trial was conducted to assess the effect of dietary protein levels on growth performance, serum indexes, PI3 K/AKT/mTOR/S6 K signalling pathway and intestinal microbiota of abalone Haliotis discus hannai. Abalones (initial body weight: 15.88–16.54 g; initial shell length 41.70–42.40 mm) were fed nine isoenergetic (~16.08 kJ/g) and isolipidic (~42.0 g/kg) experimental diets with 93.5, 116.9, 151.1, 191.8, 230.3, 275.9, 320.3, 360.5 and 405.9 g/kg protein contents, respectively. Results showed that the optimal dietary protein level for H. discus hannai was determined as 259.4 g/kg through second‐order polynomial regression analysis for weight gain rate (WGR). Serum TP and urea nitrogen levels were significantly increased when dietary protein levels were higher than 320.3 g/kg (p < .05). The highest gene expressions of phosphatidylinositol 3 kinase (PI3 K), target of rapamycin (mTOR) and ribosomal protein S6 kinase (S6 K) in muscle were found in the treatment with 275.9 g/kg of dietary protein. The excessive dietary protein level (405.9 g/kg) significantly decreased the gene expression of S6 K. Meanwhile, abalone fed with 275.9 g/kg of dietary protein exhibited the highest microbial diversity in intestine as measured by Chao richness and Shannon diversity index. In conclusion, dietary protein level reduced from 259.4 g/kg to 154.0 g/kg or increased from 259.4 to 323.0 g/kg, the WGR of abalone might be depressed with 5% likelihood. Over high (>360.5 g/kg) or low (<151.1 g/kg) dietary protein levels had negative effects on growth performance, serum indexes, PI3 K/AKT/mTOR/S6 K signalling and microbial diversity in intestine of abalone.

“…However, several bacterial metabolic functions existed significant differences between different groups at KEGG level 3, especially the intestinal bacterial of the fast‐growing shrimp had a higher level in the ‘proteasome’ function. Shrimp has a high demand for feed protein; high protein utilization is beneficial to the growth of shrimp (Lalramchhani et al., 2020). Thus, the high levels of proteasome metabolic capacity of the intestinal bacterial may facilitate the feed protein utilization and are beneficial to the growth of the shrimp.…”

Characterization of bacterial community in intestinal and rearing water of Penaeus monodon differing growth performances in outdoor and indoor ponds

Penaeus monodon provides a high‐quality protein source for humanity, and pond cultured shrimp often presents asynchronous growth. Microbial communities are important for the digestion and immunity of shrimp. Therefore, in this study, we investigated the bacterial characteristics of the intestine and rearing water of asynchronously growing P. monodon that were cultured in outdoor and indoor pond respectively. The results showed that the bacterial community of the rearing water was more complex than that of the intestine; the fast‐growing shrimp in the indoor pond had higher intestinal bacterial diversity. Besides, the dominant bacterial composition of the water was more complex than that of the intestinal. Specifically, the abundance of Proteobacteria in the intestine was consistent with the growth performance of shrimp in the outdoor pond, which was exactly the opposite in the indoor pond. At the genus level, two cyanobacteria, Limnothrix and Cyanobium PCC‐6307, were dominant in the indoor and outdoor water respectively. In the outdoor pond, Bacillus was dominant in the slow‐growing shrimp intestines, while Vibrio was dominant in the fast‐growing shrimp. The intestinal microbes of the fast‐growing shrimp had higher proteasome metabolic capacity. These results can provide new insights into microbiome characteristics involved in the asynchronous growth of shrimp.

“…However, Gopal and Raj (1990) stated that feeds with protein content greater than 40% decreased growth, while Bhaskar and Ali (1984) pointed out that the optimum dietary protein requirement decreases as the shrimp grow. In addition, the best performance in terms of growth and survival of P. indicus in grow-out conditions was achieved when fed with a diet containing 35% CP (Lalramchhani et al, 2020). Comparatively, the results of this study revealed that protein content of the diet can be lowered to 34% without negatively affecting the growth, survival and productivity of P. indicus cultured in earthen ponds from PL20 up to adult size.…”

“…In particular, protein is essential and understandably the most expensive component of shrimp feeds; hence, it is critical to develop a cost-effective feed that provides the best protein for the shrimp (Velasco et al, 2000). The presence of inadequate protein in feed adversely affects cultured shrimp's growth and health condition, though it may also lead to reduced environmental impact and improved water quality (Güroy et al, 2012;Lalramchhani et al, 2020). Thus, an optimal protein level, which is generally higher in crustaceans, is required to attain maximum growth and reproduction (Ashokkumar et al, 2011).…”

“…The protein requirement of juvenile P. indicus was found to be between 25 and 43 per cent (Ali, 1994;Colvin, 1976;Gopal & Raj, 1990). Moreover, a 30%-35% protein level in a practical diet was reported to be optimum in a P. indicus grow-out pond culture (Lalramchhani et al, 2020). However, there are no reports on the protein-level requirement of P. indicus that can contribute to good growth efficiency and productivity while assessing and lowering the cost of production in a grow-out culture.…”

The growth efficiency, productivity and economic viability of Indian white shrimp (Penaeus indicus) fed with diet containing 40% (CP high ) and 34% (CP low ) crude protein (CP) levels were determined in a 90-day grow-out culture trial. Growth parameters including average body weight (ABW), specific growth rate (SGR), survival and feed conversion ratio (FCR) were not statistically different. CP low had lower overall shrimp production (797.53 kg/ha, DOC 90), but was not significantly different from CP high (843.78 kg/ha, DOC 90). The mean values for the water parameters of both treatments, such as DO, pH, salinity, temperature, TAN, NO 2 -N, NO 3 -N and PO 4 -P, also showed no significant differences. However, the TAN values of CP high were consistently higher from day of culture (DOC) 63 and increased significantly (p = .048) at DOC 90. Furthermore, the total bacterial and Vibrio counts in both treatments were not significant throughout the culture period. The economic analysis revealed that CP low obtained higher net profits (6093 USD/ha/year), return on investment (72%) and discounted benefit-cost ratio (1.73). The current study found that feeding a low protein diet to P. indicus is economically viable and profitable and results in improved growth efficiency and productivity while also improving water quality and lowering nitrogen discharge.
